Knowing about the shadow manipulation within YIN nature release made Shikai excited. As a guy who read many manga's and novels along with some hyped anime he had a plan to be a well-known figure in the future fully depending on the Shadow manipulation and it's vector.
well, that's for another time.
Time passes on Shikai was now 6 yr old, it relates Naruto being 5 yr
Shikai thinking " Didn't that Naruto failed 2 times in the exam so I guess it's time for him to be in the academy, shit I can't get the timeline, remembering of the timeline will the butterfly effect be big or small considering the fact that the previous me was dead in the original scenario ?!"
"well, let's hope it won't be a drastic change I can't cope with it,"
During the time laps, Shikai learned more about how to maintain chakra revolution and changing it into a chakra pool but he wasn't talented in this area so it hasn't been done yet but on the other hand, Shikamaru had already made a small pool,\
scolding Shikamaru "tch! how did this happen this guy was even sleeping and listless all day"
Shikamaru turning away the eye" troublesome, don't say that brother ! it's bothersome in its own way"
Shikai "whatever u dumb so Choji again asked for money to eat huh !hahaha"
Shikamaru " well he don't have anything other to do except for eating anyway,if you want to form a chakra pool try stimulating gaps between pores "saying this Shikamaru again turn aside falling asleep
POV Shikai
Shikai thinking about his brother habit just went with the flow and finally at the age of 7 formed a chakra pool which was like a drop of water so he decided to give a rating for the chakra pool and combat power of people according to their chakra pool remembering the plot of the original story
comparing his chakra pool to Genin it is about 0.1 and Shikamaru about 0.3
Genin -1 to 2
Chunin-3 to 4
Special Jounin-5
Jounin-6 to 8 as they have low-level Jounin to high level
Elite Jounin-9 and finally the level breaking point
Kage level -10
Shikai on a talk with his uncle remember the classes taught on academy
"Chakra theory
Basic Techniques: Bunshin (Clone), Henge (Transformation), Kawarimi (Replacement), shuriken and kunai throwing, hand-to-hand combat
Kunoichi are taught flower arrangement"
"so for this level, I have to at least have level 1!sigh"
"isn't now around the time when the Uchiha coup plan happen and Itachi kill all except Sasuke, well it ain't for me to think without social level and personal power I can't walk toward the political pit",
And due to Danzo, the villagers have started to give cold look toward Naruto, too much to think about but remembering his future, and protagonist plot he won't go astray "
now dealing with the personal problem I only have the capability of forming a chakra pool of special Jounin which is basically chunin , and again the shadow manipulation in the Naruto world is so backward too much to do since learning the chakra and its various ways, I have a way for creating a new jutsu but it will take time at least until I become level 1,
POV END
time passes and its a time for academy,
Shikaku " Shikai, Shikamaru, you both are now 8 yr old so now I hope you can go study in the academy and not laze out all day, and remember you have to take care of Ino, Cho relation and Naruto, at least don't hate him I hope you won't betray my trust"
Shikamaru "hai! okay , bothersome school"
Shikai just nods his head
Next Morning
arriving lazily into the class seeing many children it's already bothersome
here Shiaki saw many faces of the character and gave the name
Shino Aburame-insect guy
Choji Akimichi-fat guy
Sakura Haruno-big forehead
Hinata Hyuga-little girl
Kiba Inuzuka and Akamaru-dog and dog guy
Shikamaru Nara-the listless mind
Naruto Uzumaki-the loudspeaker
Ino Yamanaka-jealous queen but beauty Uchiha Sasuke- EMO duck lol
other than the Shikai remember three other main influencers; Rock Lee Neji Hyuga and Tenten
Thinking all this he made his mind to try his love life with Ino Yamanaka, well a blondie who became a babe in future, just imagining gave a satisfying feeling then he again questioned about his look well having a hair tied, a little built up than Shikamaru, face, and hairstyle of Kuchiki Byakuya, and the main point is having scar along the eye shows some charm, feeling all this Shikai was naturally convinced about his love life throwing the shame of 30 yr old guy(22 previous 8 now).
Finding the seat, sitting down he looked toward all the members talking,playing and shouting then he quietly starts forming a chakra cycle , he has difficulty in forming chakra pool not like Naruto who have chakra pool enough to neglect nine tails corrosion.
having many plans for the future Shikai first plan was to be a low key not to attract any attention just acting normal but he didn't know that the third Hokage had already seen him through is glass ball secretly
Third Hokage "Shikaku ain't this child your brother's son?, he is mature for his age he might have a bright future ahead,!"
Shikaku filling out the documents "well! he is a good boy, have a great character for a child but sorry to disappoint you he can only form chakra up to special Jounin level due to injury on nine tail attack"
The third Hokage " well that's bad, but i hope he won't hate Naruto for that due to all gossip around the village!"
he shifts his view toward Naruto who was talking with Inuzuka shouting" I'm not a new guy"
and helplessly sigh!
The teacher came into the class and started talking about the chakra cycle and knowing all have formed at least the chakra pool he then started the main topic of '"Bunshin(clone)"' as the start of a shinobi journey
Shikai knowing his inability of understanding clearly was listening carefully ,as to not miss any point as this is the main and basic technique for his own C-CLASS JUTSU;;;; NAMED --
